4:58 Brooks checking that side view mirror for that Blondie he just passed 😂

Even with power going down with mileage the launch is so brutal the difference in ET is negligible not even a 10th of second.

I noticed this a while back. Seems like all the Plaid videos (not just Brooks) went from trapping 150-152mph, to trapping 146-150mph.

A tenth? Not bad. Any car run decently hard for 40k miles and a few years will lose a bit.

"who ever pushes down on the accelerator first wins" ahh race

You can also see your first months best Quarter mile time vs your earliest best quarter mile time to do a comparison

I’ve owned a 9 second street/strip car since 2004. I need to know how to get 40k miles of street driving plus more than 500 passes on the drag strip without having to pull the engine every other season and re ring, new bearings, rebuilding the turbo, replacing head gaskets. I mean, it’s all part of the journey of having a street capable 9 second car but man I’m getting older and I’m about tired of working on it all the time. Basically what I’m saying is if you’ve only lost 1/10 and a few mph and almost never have to do maintenance on it then that’s considered a win. Stop complaining 😂😂

As for technical understanding of WHY trap speed is lower on OLD plaid here is the reason: The battery voltage sag more because of battery age. This translate to lower maximum kW = lower trap speed. The internal resistance of the battery is probably a bit higher after it aged. One way to verify that is to use one of the app that allow you to measure max and min battery voltage and record the minimum battery voltage during one pass and compare results with the NEW plad. You will get the answer.

We need a Plaid Plus 😂

My Plaid has 26K. I'd be in for the Plaid + if they come out with it.

Might be time to actually DYNO it, and see if it still outputs the same horsepower and torque. I feel like there is less torque, and this is 100% software related.

To be fair, your 97% SOC is not the same as his 97% SOC when you account for degradation.

Same boat as you. My 22 MSPlaid has 46k miles and 60-130 is now best of 5.10. Won’t touch anywhere in 4 seconds.

Well Brooks back in the old days we would pull the motor and re-brush it and put new brushes on the front of the guide the kept the car in the slot 😛

3:56 two red plaids launching side to side looks like one car is racing next to a giant mirror 😂

Thanks for showing this comparison!

I love the new Tesla red color! In the end, your driving skill won the day. But it still was close enough that a better driver in either car would win. It says so much that the older Plaid can still run 9.3-9.4 in the 1/4 mile. I wonder how well an exotic car would have held up after 37K miles, and a LOT of drag racing?

This should actually be a class action lawsuit. I own a plaid, paid $140k for it plus tax, just for them to cut prices I'm half in a year pretty much, and for my car to get dramatically slower later on.

I don't think it's losing 90HP. Probably more like 50Hp up top only. Losing 90HP would be essentially losing almost 9% power. You would be more than a 10th slower and trap would be gapped more if that were the case. A 5% loss is more in line with those numbers.

Great content, as always, Brooks. I would say that the old Plaid is still above and beyond quick even with its minimal loss. I wonder how it will perform with 60K miles on it. Too bad those brakes heated up so quickly. About the CCAN Action Fund: I always thought you were more of a Lincoln/Reagan type, not a FDR/JFK type.

Think about what would happen to a 1,000+ HP ICE car if you daily drove it and raced it on the weekend. It wouldn’t even make it to 20k mile much less 30k+ miles. Honestly, that isn’t as much degradation as I thought it would be.

ICE cars usally gain horsepower as they get more miles, sometimes up to 100k, which is is where they begin to lose power due to blow by. At 37k an ICE engine is just starting to get into it's strongest running. This is all depends on how well it's maintained, of course.

I think so too : PLAID PLUS I can’t wait

Dragtimes Great Video I think it's awesome that you showed how Tesla Model S Plaids lose horsepower over time and I think it's crazy and Happy 4th of July to you your family and all of your Subscribers

At only 37k miles thats not fun to see, no winder EVs depreciate so fast, gas engines are just getting started at 37k miles.

You mentioned the state of charge for both cars at the beginning as being 97%. What was the state of charge for both after your runs were completed? Did they deplete at the same rate?

Great Video. I just purchased a draggy and I still get 3.1 (w/ roll out) 0-60 with my 2020 M3P with 90K miles with stock wheels and tires. Haven't had enough road yet to do the 1/4 mile. Interesting!

I bet an ICE with 37k miles is faster than when it was brand new.

Now Lucid is hammering the Plaid run after run. Doing all out runs is also temp regulated. If you live where it is very hot then the car will go with safety over speed. Some factors but Brooks you would know if you have run all these cars. LOVE THE CHANNEL !!!!! You put em to the test.

This is really a loaded question. Battery tech and charging are still relatively new at this scale and Im sure improvements will be better over time. How do you charge? We know you run the car harder than the average consumer so does that play a factor? What are your charging habits, etc., etc? All of these unknowns play a part in answering your question. I also wonder if a software update can resolve the issue? Nice color on that Lucid in the background btw.

Great video Brooks! I agree, Tesla needs a Track Pack option from the factory.

I have a 2018 bolt i can take you on bro

Nice video Brooks , my 2021 S Plaid OG pre new headlight taillights like yours and it only has 16,000 miles but I have never ONCE used launch control nor taken to the track so no idea what loss at this point but that is slightly disappointing. Hope Tesla updates the plaid soon like you mentioned , Plaid + w more power and carbon ceramics etc , I’m down for an upgrade too at that point if it’s a sapphire killer 🙏🏼👌🏼💪🏼

I would enjoy seeing what it does up here in Colorado. My refresh 22 MS (non plaid) ran a 10.61 so it would be interesting to see with the altitude and air density what the plaid would run.

Another knock against EV's.

You should compare with your old time slips instead because different cars can vary

At least it depreciates faster than it gets slower. 😂😂😂

I was recently in the market for a C8Z06, I wanted a 1LZ Z07 car with the comp seats, aka stripper with all the perf goodies, but due to the shortages my allocation got pushed WAAAAY back. Not surprised considering I negotiated a MSRP price. So I took my DP back and used it to buy the cheapest Plaid in the area, ended up with a 47K mile car, that I later found out had been used as a Turo car. When I finally got a L2 charger installed at home I did a Battery test and discovered the battery was only at 86% health. My range is not great, but I don't use the car for road trips really, I have 2 toy cars for that, one a Focus RS, and the other heavily modified 89 TransAm GTA. Your trap speeds make me feel a bit better, as when I discovered the battery health was at 86% I was kind of frustrated, thinking about the performance I had lost from not buying a new one. I saved ALOT buying used. So far, I've trapped about 144mph on draggy, but only when the battery is above 85%, under that trap speeds seem to drop, at around 70% I think its around 141mph, and when I get near 50% there is a huge difference in acceleration, I'd say like Sport vs Plaid mode feeling. My bet is that as a Turo rental car, this car was frequently supercharged as the only charge method, and probably kept at at or near 100% so it could be delivered to renters with a full SoC. Which negatively impacted the battery health. That said, I did save over $30k on it as a used car.

Ive I asked a few times how/if I can get a heads up when yall are planning to go to the track. Ive been a viewer for a time and live right down the road from Bradenton Dragway. Would enjoy coming to watch.

Interesting results. Sounds about right for the current battery technology. Once solid state batteries are refined that should help maintain HP in E cars.

Brooks, on average what has your EPA distance been estimating in the display at full charge at this mileage? (assuming it’s set for 21” wheel setup / 348 mi projected range when new)

Someone like Brooks has enough money to buy a new plaid every couple months and not even thinking about the cost. He'll make more money from this video than what a new plaid cost... Lol

Since they had different tires and rims, I am not sure we should look too much into the figures or?

You need to consider the wheel size 255!?, tire pressure, and suspension setup. I believe your speed loss is due to the tires, and another potential issue could be that the suspension is not tightened to the maximum.

My Model 3 has a 60-130 time of around 12 - 14 seconds, so even with the degradation that Plaid is still on another level lol.

37k hard miles.. but great durability test

That second race 4:24 you guys launched almost exactly the same! Less than .08 difference and 4mph is not bad at all with 37,000 miles. Still super fast and will still whoop most anything on the streets. Still a low 9 sec car and you've beat on that thing.

Good video. can you advise what your tire replecment / maintenance looked like over the 37k. thks

Interesting comparison! Brook, are you gonna switch from the Plaid to the Sapphire?

It might be because if racing it so many times, It would be interesting to see you race against a Plaid with similar milage that wasn't raced so much

The Tesla Plaid Channel guy has over 1900 time slips on his PLAID and the MPH is still within 1 mph from his best times! granted he has lighter wheels, but not much.

I have to like this video especially for the narration in the ending. Thanks for the calculation! 90hp is a lot, especially if it keeps going down (does it?)

What I've learned is that EV fans are not very intelligent.

For anyone wondering its down to the battery. The motors are still perfectly capable of producing the 1000hp+ and making the car do 215mph (with speed limiter removed), but the battery will have some degredation. Could also do with Tesla limiting software somehow. Notice this will mainly be seen in the Plaid which is pushing the battery to the limit. But on the Long Range version with 650hp or whatever, you wont notice much, if any, difference after 37K miles

That R/T on run 3 😎

Different trend, Different weights of both driver's Different reaction, and different tires it going to make a difference.

I think the difference is a radiator that isn’t performing as a brand new one is. My radiator had a ton of dirt and debris which made my fan loud and work hard which affected the performance. Could be what’s slowing down the times and performance. Might be worth looking into brooks.

Tesla is also notorious for updating/changing/tweaking things and not mentioning it anywhere on their site or documentation. They have prob made some small changes too, its been three years since it came out.

100%! Mine ran 9.30@151 when new and after 30,000 miles best it’ll run is 9.50@146

For context most battery deg happens with in the first couple years of ownership before falling off a lot. So this isn't surprising. Both cars at 100% would reduce the difference by a lot. Also petrol cars are FAR from immune to this kind of performance lose.

Amazing how consistent the acceleration is.

Great video

In my opinion, the way the car is operated also affects the decrease in car performance. If you accelerate it so often using full power, the car wears out faster than operated calmly. Especially the battery

Hopefully they'll have a new version by next year. They seem to do the big changes every 4 years or so. This battery degradation makes me not want a used one because who knows how the previous owner treated it.

If you could run the new Plaid against a lower milage older one to see if the mileage and wear and tear may be the reason your car is slower. I think with anything mechanical, over time performance can diminish... I agree there should be a carbon ceramic brake option.

So did your wheel setup have something to do with being slower? Possibly not as aerodynamic?

Power density drops off twice as fast as energy density. A drag race is about power density. Still, this beats ICE vehicles, especially over 500k where the ICE will have less than half its original power and the Plaid would probably have 85% of the original power and 95% of original range. For non-plaid, it would still have 100% of the original power since its power requirements are less than 85% of the plaid.

Time for a new one!!!!!

It depends a lot on the charging habits and typical SOC the car has seen. Was it charged to or near 100% quite often? Supercharged to 100% often? Did it sit at 100% SOC for long periods? When it sits for longer periods, is it kept between 30-50% SOC? The power falloff from 100% down to ~65% is a tenth or less on a fresh battery, so there’s no need to charge the car to 100% a lot for daily use. Hell, it’ll still run 9s at a 20% SOC. Keep it between 50-80% max for daily, just charge to 100% right before you go to an event or something where you’re trying to put up your best possible numbers. When you do charge to 100%, try to time it to complete right before you leave so it’s not constantly recharging it from 98% to 100% over the time leading up to your event. Battery care has a slight learning curve to adapt to in order to keep it near full capacity for as long as possible. If these things were all done, then I’d venture to say that the battery is degrading at a slightly more rapid pace than it should, given that it’s not another problem that is. You may want to do a battery health check through the app to get an idea where it’s sitting. Love the videos. Keep it going!

Great vid!! +1 for everyone who's commenting about battery degradation/age (especially if you Supercharge often). One other weird consideration: I really appreciate the way both cars started with equal SoC, but were they running the same Software version?? Just to ensure it's as apples-to-apples as possible!! Thanks!

I apologize if already mentioned. What about the difference in wheel weights? I believe you’re running light signature wheels which may/should affect the moment of inertia and therefore overall race outcome. Maybe switch wheels and re-race?

I would check a couple others to be sure , could just be that day onboard computer could be like yahhhh we aren’t feeling it today

How does your Dragy compare today with your Plaid when it was new? That would give you the most accurate measure of performance over time. There is definitely a hp difference between the two at this point.

Battery degradation is just a fact of life with all EV's. It's totally fair if you know what you're getting into and Tesla's own warranty even mentions degradation happens. The power is simply limited by the batteries ability over time. Within the first year you lose 5-10% then it tapers off after that. Losing a tenth and a bit on the top end after high mileage isn't the greatest but it's still a drivers race and it's still beating almost everything and anything costing several times as much money. The value proposition is still extremely hard to beat. You wanna maintain your power, lighten the car a bit. Swap out the seats with lighter ones, put lighter rotors on it, CF trunk/frunk. All that said, next gen solid state and sodium batteries are going to really take things up a notch and degradation will be even less prominent. Right now we're just stuck with mid-life battery technology before things like this become less of an issue. I do hope Tesla upgrades and refreshes the S soon though... it's really getting long in the tooth and could use some further improvements.

Lots of variables: tires, battery degradation, motor wear, true SOC. Hard to pin down any one cause. Or it could just be regular variation between builds.

reliability wins, both are great!

9.3 and 9.4 is still so fast. Sweet

A 5mph loss of trap speed is significant. I ran it through a few 1/4 calculators and most show about a 100hp difference with a Plaids weight and a 5mph difference around 145-150mph trap speed. So about a 10% loss of power for the older Plaid. I wonder if this is true for Plaids in general with higher miles/years on them or just your particular car? I wonder where the loss is occurring? the battery? motors? friction some place? are brakes dragging?

The Second Law of Thermodynamics states that the state of entropy of the entire universe, as an isolated system, will always increase over time.

Bms of battery contros everything. The internal resistance of the cell may increase with time, more heat and BMS reduces the output. LPF battery is the future for longevity. NMC is for performance.

You should do a test where both Plaids have about 40k on them, but one that has been babied rarely do they on the accelerater and one that gets dogged out. I have a feeling there will be a difference in the two.

My son said, are they racing? I said YES why? I don't hear anything.

I see what you sayin about the more miles the more power you lose but keep in mind, if you preconditioned the battery (as if you are going to a super charger) the batteries warm up and give you max performance. Please keep that in mind when you racing with the plaid plaid plaid plaid 😝😝😝

Regardless, the model S design looks the best out of all the family cars and most practical with the liftback.

I'd be more concerned that it has likely lost 50% of it's value already than being a tenth or two slower in the quarter. EV depreciation is pretty bad, but Brooks seems to have almost unlimited $'s.

Everyone on here bitching - just run the Overnight BATTERY test to see what your DEGRADATION is ! lol

Damn those cars are so damn hot! Sucks bout the HP loss, but who gives a damn, u still punish most cars out there!

Nice to see a real steering wheel in the 24..

Brooks... think about the Next Plaid??? I wonder what is on the Tesla plans for the next Street Track Plaid, with Maybe Plaid + and the suspension upgrades??? Very interesting! Brooks, You Deliver! Thanks! Can you do a reset on your car? Or take it in for a reset? Let us Know! Exciting!

Never thought I would be so bored watching such a fast race. 🚗 🔋 🔌 🥱

I wonder if Tesla has any suggestions on the cause of the degradation. Performance reduction caused by inverter, battery, drivetrain component or other?

It’s because Tesla use brushed motors. It’s a little bit past its half life. They probably also have a system that drops performance to compensate for overall longevity of the motor and batteries.

This is most likely dues to a bit of battery degradation and also motors wear. But very little difference in general, maybe comparing a 100K miles vs a 1K miles would be a better test to see what real degradation we have got. It would be good to also run a battery test on both vehicles to compare those numbers.

One thing Tesla is known for is immediately implementing design improvements into the production line instead of waiting for model year changes or the traditional design cycle refreshes. Do we know that this new plaid is the same car inside? Did Telsa improve the inverters, motors, BMS etc. is this really comparing apples to apples? They could have easily changed something internally that improves the power delivery curve, even without changing the HP rating.

It’s powered by a thermite bomb. Lots of power for a few minutes followed by a slow burn for two days.

Let's ask Elon to make Plaid+ OR increase more HP on current Plaids, come on guys let ask him about to beat that ugly lucid !!!👍

Try find the motor serial numbers and see if are the same, Tesla could be using a different motor now in the more recent, like on the new m3p the us version is faster than the European version so could be something like that. And don’t forget they made a little update in the brakes in the more recent version so they could unlock I but more the top speed.

A little bit trap speed is lost due to wheel & tire size/diameter. I’d say it’s 3.5 mph lost due to degradation at most. Rest is due to different wheel/tire setup

Look at @teslaplaidchannel he’s like the only plaid owner consistently hit 9.2s on a 2021 or 2022 plaid s & he also does a lot of testing with what tires slow you down the most and the results are actually pretty interesting.

Ice will likely gain after 37k miles: cause owner can’t resist modifying it by then. Still should look at all the old time slips and the degradation in trap speed will be linear I bet. One thing unrelated for Brooks: after owning a plaid for 30k+ miles, is it still worth it or just a 1/4 mi trick compared to albeit [slightly] slower (!) Hurrican/sf90/gt3/720?
